Title: Valve core connecting and disconnecting tool
Inventor: FUKUDA NORIAKI
IPC: B60C25/18
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To securely pinch a head of a valve core by inserting a barrel part for holding a tool for rotation and a stopper for holding the tool for rotation into a holder part. SOLUTION: Before installing a valve core connecting and disconnecting tool in a valve core 13, a barrel part 2 thereof is drawn to a stopper 3 side so as to open a stopper 9. A tip of a holder part 1 is lightly pushed to the valve core 13, and a shaft 15 of the valve core 13 is inserted into a shaft pinching hole 7 through a shaft constraining hole 6. The barrel part 2 is slid in the direction of the tip of the holder part 1 so as to narrow a slit 9. As a result, the shaft constraining hole 6 of the holder part 1 securely pinches the shaft 15 of the valve core 13, and the shaft pinching hole 7 securely pinches the tip of the shaft 15 of the valve core 13. Thereafter, the barrel part 2 or the stopper 3 of the valve core connecting and disconnecting tool is turned so as to connect or disconnect the valve core 13.

Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To produce a magnetoresistance effect (MR) type head not causing the waving of the MR element layer and to therefore improve magnetic characteristics. SOLUTION: A lower shielding layer 3 is formed on a substrate and a resist layer 31 having a flat surface is formed on the lower shielding layer 3. The resist layer 31 and the surface of the lower shielding layer 3 are subjected to ion beam etching under conditions which ensure the same etching rate of the layers 31, 3 to flatten the surface of the lower shielding layer 3. An MR element layer is formed on the flattened lower shielding layer 3 and a pair of permanent magnet layers are formed on both sides of the MR element layer in a direction in which electric current is supplied.
